Build Identifier:

I created a filter function:

CREATE filter function strmaxdist(s1 string, s2 string, k int)
external name str.maxdist;

to be used as:

FROM a,b
WHERE a.s strmaxdist(2) b.s;

It works fine if I create and use the filter function in the "sys" schema.

If I create and use it when I am on a different schema, then I get:

Subquery result missing

Reproducible: Always

If I issue the same CREATE FILTER FUNCTION command in both the "sys" and my custom schema, then I can successfully use the filter function in the custom schema.

This is fixed (only) in default. There we changed filter functions calling interface as well (ie change to [a1,a2] filter.func [b1,b...].
